TL;DR: An undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period, shows a slow decline in temperatures that marked the initiation of the last glacial period.
Journal ArticleDOI
High-resolution carbon dioxide concentration record 650,000–800,000 years before present
Dieter Lüthi,Martine Le Floch,Bernhard Bereiter,Thomas Blunier,Jean-Marc Barnola,Urs Siegenthaler,Dominique Raynaud,Jean Jouzel,Hubertus Fischer,Kenji Kawamura,Thomas F. Stocker +10 more
TL;DR: It is found that atmospheric carbon dioxide is strongly correlated with Antarctic temperature throughout eight glacial cycles but with significantly lower concentrations between 650,000 and 750,000 yr before present, which extends the pre-industrial range of carbon dioxide concentrations during the late Quaternary by about 10 p.p.m.v.
Journal ArticleDOI
Orbital and Millennial Antarctic Climate Variability over the Past 800,000 Years

TL;DR: It is suggested that the interplay between obliquity and precession accounts for the variable intensity of interglacial periods in ice core records.
Journal ArticleDOI
Atmospheric CO2 Concentrations over the Last Glacial Termination
Eric Monnin,Andreas Indermühle,A. Dällenbach,Jacqueline Flückiger,Bernhard Stauffer,Thomas F. Stocker,Dominique Raynaud,Jean-Marc Barnola +7 more
TL;DR: The similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations.
Journal ArticleDOI
Stable carbon cycle-climate relationship during the Late Pleistocene.

TL;DR: A record of atmospheric carbon dioxide concentrations measured on the EPICA (European Project for Ice Coring in Antarctica) Dome Concordia ice core extends the Vostok CO2 record back to 650,000 years before the present, suggesting that the relationship between CO2 and Antarctic climate remained rather constant over this interval.
